Preview a 3D texture

To preview a 3D texture, do one of the following:

• Use the Inspector window.
• Draw the 3D texture in the Scene view.

Use the Inspector window

To preview a 3D texture, select the texture in the Project window. In the Inspector window, Unity displays the preview of the texture at the bottom of the Texture Import Settings window.

There are three different 3D texture preview modes available:

• Volume mode displays the 3D texture as a translucent cube. Click and drag the cube to rotate the preview.
• Slice mode displays a 2D slice of each of the three axes of the 3D texture. Use the X, Y and Z sliders to select the slices to preview.
• SDF mode displays the 3D texture as a signed distance field (SDF) in 3D space.

Refer to 3D texture preview reference for more information.

Draw the 3D texture in the Scene view

Use the Handles API to draw the 3D texture in the Scene view. The Handles API lets you use custom gradients and configure how you draw the texture.

Refer to the following for more information:

• Handles.DrawTexture3DVolume
• Handles.DrawTexture3DSlice
• Handles.DrawTexture3DSDF
